I have very sensitive skin on the parts that do not get sun. Where I have brown skin because of the sun does not give me anything, more where the skin and white appear huge bumps in the back belly and thighs. Do I need to get sun in these areas?
Expert answer:

Exposure to the sun causes skin cancer, what you need is to seek a medical dermatologist for him to make a diagnosis of your skin problem and with the diagnosis get a treatment.
